Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a support for objects, more particularly to a combined chair and object support for video equipment, telescopes, drawing boards and the like.

2. Description of the Related Art

Stands for supporting a variety of objects, such as cameras, telescopes, drawing boards and the like, are known in the art. However, the conventional stands are not equipped with means for sitting of the user, and thus require the use of a separate chair.

SUMMARY OF THE INVENTION

Therefore, the object of the present invention is to provide a combined chair and object support for video equipment, telescopes, drawing boards and the like to overcome the aforementioned drawback of the prior art.

According to this invention, a combined chair and object support includes a chair leg assembly, a seat member, an upright support post and a linking member. The chair leg assembly has an upper leg end, and a lower leg end opposite to the upper leg end and adapted to be placed on a ground surface. The seat member is mounted on the upper leg end of the chair leg assembly. The upright support post is adapted for mounting an object removably thereon. The linking member is formed with a first coupling end connected to the seat member, and a second coupling end connected to the support post, thereby forming a horizontal spacing between the seat member and the support post in a longitudinal direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before the present invention is described in greater detail, it should be noted that same reference numerals have been used to denote like elements throughout the specification.

Referring to FIGS. 1, 2 and 3, the first preferred embodiment of a combined chair and object support according to the present invention is shown to comprise a chair leg assembly 2, a seat member 3, an upright support post 5 and a linking member 4.

As illustrated, the chair leg assembly 2 has an upper leg end 211, and a lower leg end 213 opposite to the upper leg end 211 and adapted to be placed on a ground surface. The seat member 3 is mounted on the upper leg end 211 of the chair leg assembly 2. The upright support post 5 is adapted for mounting an object, such as a camera 513 (see FIG. 2), removably thereon. The linking member 4 has a first coupling end 411 connected to the seat member 3, and a second coupling end 431 connected to the support post 5, thereby forming a horizontal spacing between the seat member 3 and the support post 5 in a longitudinal direction, as best shown in FIG. 2.

The chair leg assembly 2 includes a plurality of known telescopic legs 21. The chair leg assembly 2 further includes a coupler 22 at the upper leg end 211. The telescopic legs 21 are connected pivotally to the coupler 22, thereby permitting folding of the chair leg assembly 2. The seat member 3 has a bottom side 311 formed with a connecting post 34. The coupler 22 has a vertical coupling hole 22′ for receiving the connecting post 34, such that the seat member 3 can be mounted on the chair leg assembly 2. Preferably, the coupler 22 of the chair leg assembly 2 is provided with a retaining unit in the form of a threaded rod 23 for retaining removably the connecting post 34 in the coupling hole 22′.

A known clamp 35 is mounted on the bottom side 311 of the seat member 3. The first coupling end 411 of the linking member 4 is clamped by the clamp 35 to mount removably the first coupling end 411 to the seat member 3.

The linking member 4 includes a first link 41, a second link 43, and a first angle-adjustable joint 42. The first link 41 is formed with the first coupling end 411 and a first pivot end 412 opposite to the first coupling end 411. The second link 43 is formed with the second coupling end 431 and a second pivot end 432 opposite to the second coupling end 431. The first angle-adjustable joint 42 is a conventional device that interconnects the first and second pivot ends 412, 432 to retain the second link 43 at a desired angle relative to the first link 41.

The linking member 4 further includes a second angle adjustable joint 45 similar to the first angle-adjustable joint 42, provided at the second coupling end 431, and connected to the support post 5 to retain the support post 5 at a desired angle relative to the second link 43.

The seat member 3 includes a central plate portion 31 formed with the connecting post 34 and mounted with the clamp 35, and a pair of wing plate portions 33 connected foldably and respectively to opposite lateral sides of the central plate portion 31. The first and second links 41, 43 and the support post 5 are foldable so as to be disposed on top of the central plate portion 31. The wing plate portions 33 are foldable upwardly relative to the central plate portion 31 when the first and second links 41, 43 and the support post 5 are folded on the central plate portion 31, as best shown in FIG. 3.

Preferably, each of the wing plate portions 33 is formed with a grip hole 331 to facilitate upward folding of the wing plate portions 331 relative to the central plate portion 31.

In this embodiment, the support post 5 includes a telescopic post 52 having an upper end provided with a known mounting device 51 for mounting the object removably and adjustably thereon.

Referring to FIG. 4, in the second preferred embodiment of the present invention, the object mounted on the support post 5 is a bracket 513. A board rail 514 is supported by the linking member 4 in a transverse direction transverse to the longitudinal direction. The board rail 514 is adapted to cooperate with the bracket 513 to retain a drawing board 515 on the support post 5.

Referring to FIG. 4, in the third preferred embodiment of the present invention, the combined chair and object support further comprises an auxiliary leg unit 44 having an upper leg part 441 connected removably to the linking member 4 via a known clamp 442, and a lower leg part 443 opposite to the upper leg part 441 and adapted to be placed on the ground surface. The auxiliary leg unit 44 includes a pair of telescopic rods 444. Thus, the drawing board 515 can be stably supported on the ground surface.

Referring to FIG. 6, in the fourth preferred embodiment of the present invention, the support post 5 is in the form of a telescopic post having an upper post end 531 adapted to be mounted with the object, a lower post end 532 adapted to be placed on the ground surface, and a middle post section 533 between the upper and lower post ends 531, 532 and connected to the second angle adjustable joint 45 of the linking member 4.

In view of the configuration of the combined chair and object support, the user need not stand when the present invention is in use.

While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
